Description of key information

An algal inhibition test according to GLP and OECD Guideline 202 was performed. DMH was tested at a nominal concentration of 1000 mg/L. Exposure of Pseudokirchneriella subcapitata gave EC50 values of > 1000 mg/L and correspondingly the NOEC was 1000 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L
EC10 or NOEC for freshwater algae:
1 000 mg/L
